The Sun Hydraulics DMDAMBV248 (DMDAMBV248) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and reliable operation under high pressure conditions, with a fatigue rating for 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times particularly in pilot control applications where capacity is less critical. The DMDAMBV248 requires no minimum hydraulic pressure to operate, making it versatile for various applications. It incorporates a wet armature design, meaning the working fluid surrounds the armature which can be a consideration if the coil remains energized for extended periods. This design helps in maintaining the temperature but might affect certain fluid types over time. For manual override, models equipped with D or L control have a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. The valve's compatibility with EPDM seals makes it suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, this model benefits from Sun's floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. The interchangeable coils enhance flexibility and maintenance ease by being compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 3000 psi set at 5 in\u00b3/min. The manual override requires a force of about 5 lbs at 1000 psi on Port 1 and has a stroke length of .10 inches (2.5 mm).
